Key Points

To determine whether purely mathematical comparisons of LDL-cholesterol calculation formulas can be completely and reproducibly modeled using an artificial dataset without requiring clinical cohorts.
Methodological study evaluating differences among the Friedewald, Martin-Hopkins, and Sampson/NIH equations.
Simulated an artificial dataset of n=900 constructed with realistic mathematical and statistical distributions.
Tested real-world clinical datasets including a hypothyroidism cohort (n=40) and a hyperthyroidism cohort (n=30) for comparison.
Pairwise differences between the three equations on the synthetic dataset demonstrated complete mathematical reproducibility.
Differences calculated in the clinical hypothyroidism and hyperthyroidism cohorts matched the findings from the artificial dataset.
Comparing formula-derived LDL-C values across distinct patient populations without direct laboratory measurements yields no novel biological insight.
